DPM UI-1
2ch universal input module
- 109 dB dynamic range – for the best audio performance without disruptive incidental noise
- Symmetrical inputs – high CMRR for avoiding incidental noise from crosstalk over long cables
- Power supply for call stations – monitored with selfresetting fuse
- Automatic configuration – mounting changes/deviations are detected and displayed in IRIS-Net
- Input transformer – transformers (Lundahl LL1531) can be retrofitted as an option
The DPM UI-1 is a 2-channel universal input module for the DPM 8016 PROMATRIX CONTROLLER. The audio signals are connected via screw-in Euroblock connectors. Channel A is a universal MIC/LINE input with programmable input sensitivity and switchable phantom power supply. The second channel can be used either as a LINE input (B) or as a call station input (C). Up to four DPC call stations can be connected to the PCA BUS interface.
Linear, high-precision 24-bit converters are used for the A/D conversion. The internal signal preparation uses a 48-bit name length.
